SAFETY INSTRUCTIONS
•Number of drive links.
•Level of kickback reduction. The level of kickback reduction offered by a chain is only indicated by its model number. See the Technical data section to find the model numbers of chains that are recommended for use with your model of chain saw.
Sharpening your chain and adjusting raker clearance
WARNING! The risk of kickback is increased
!with a badly sharpened chain!
General information on sharpening cutting teeth
•Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.
•A sharp chain eats its way through the wood and produces long, thick cuttings.
•The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip (B).The cutting depth is determined by the difference in height between the two.
When you sharpen a cutting tooth there are five important factors to remember.
1 Filing angle
2Cutting angle
3File position
4Round file diameter
5File depth
It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.
See the Technical data section for information about sharpening your chain.
WARNING! The following faults will increase
!the risk of kickback considerably: File angle too large
Cutting angle too small
File diameter too small
